PROCESS FOR STORING INFLAMMABLE SOLUTIONS.

Specification of Letters Patent.

Patented June 21, 1910.

Application filed September 9, 1909. Serial No. 516,975.

To all whom it may concern:

Be it known that I, CARL MARTINI, a subject of the German Emperor, andresident of Berlin Germany, have invented certain new and usefulImprovements in Processes for Storing Inflammable Solutions, of whichthe following is a specification.

The storing of inflammable liquids in receptacles containing a nonoxidizing (inert) gas, such as carbonic acid gas, is an expedient, nowwell-known, for. guarding against the ignition and explosion of suchliquids. In cases where the liquid is a so-' lution, a difiiculty hasarisen in practice owing to the absorption of a portion of the solventby the gas, which portion leaves the receptacletogether with the gaswhen the latter. is employed to force the liquid'from the receptacle bypressure. This loss of solvent causes the dissolved substance to becomedeposited and precipitated, necessitat-.

ing frequent cleaning of the receptacle,- which is not only onerous andexpensive, but' fraught with danger owing to the access of air to theinflammable liquid at the'time the rece t-acle is opened for cleaning.

y present improvement, designed more particularly for the storing ofcollodion avoids the drawback pointed out above by su tably saturatingthe gas before its admission to the rece tacle, so that the gas ma nolonger be capa le of absorbing any so vent, or at least no materialamount thereof. Preferably the liquid with which the gas is impregnatedbefore admission to the receptacle, is of the same character as theliquid in which the collodion is dissolved.

In the accom anying drawing '1 have illustrated in a iagrammaticvertical sec tion, an apparatus suitable for the purposes of thisinvention.

The inflammable solution, for instance collodion, is stored in areceptacle a, prefthe liquid restrict myself to carrying out myinvention illustrated by 65 liquids containing a erably located underground. The pipe 1) serves for filling the receptacle with saidsolution, which is withdrawn throu h the discharge pipe 0 preferablyprovide with a jacket secured to the cover e and open to the interior ofthe receptacle. The inert protective gas, contained for instance in acylinder 2', is first led through a pipe 71. into contained in animpregnating tank g, and is forced to pass through said liquid so as tobecome impregnated or saturated therewith. Preferably this liquid is thesame substance which serves as a solvent for the collodion, as forinstance, ether or 7 alcohol. The impregnated gas then passes to thereceptacle a through a pipe (2 the ends of which are securedrespectively to the '60 cover 1 of the impregnating tankg and to thecover 6 of the receptacle a.

I desire it to be understood that-I. do not the particular manner of thedrawing.

I claim as my invention:

,1. The process of rotecting inflammable issolved substance liable to beprecipitated, which consists in storing them in the presence of an inertgas impregnated to prevent its absorbing-the solvent of said substance.

2. The process of protecting inflammable liquids containing a dissolvedsubstance liable to be precipitated, which consists in storing them inthe resence of an inert gas impregnated with t e solvent of saidsubstance.

-' In testimony whereof I hereunto aflix my signature in the presence ofwitnesses.

CARL MARTINI.
